Hi,
Who knows which sas procedure corresponds to text topic node in the EM? I 'm doing a topic model (LDA)in the EG.
Thank you

Currently, it is not a single proc, but rather a combination of procs (mainly proc spsvd and proc factor), data step, and other sas code. If you build a text topic flow in EM, you can export a program from that flow. That program will contain all the SAS code necessary to generate topics and can be run in batch.

Thanks, I have found that the text topic node just uses SVD to do a topic discovery ,not LDA. And it corresponds to the hptmine statement.
